I have a T41 and I experienced the same thing yesterday.  For some
reason, I could not run gnome-volume-control.. I kept getting the "Sorry
no mixer..." message you indicated above.

This was after about 20 days of uptime, so I figured I'd reboot.  As you
noted, rebooting did not work.

I ran system-config-soundcard, which worked fine.  I ran
gnome-volume-control again and this time it worked.

Anyway, I have no helpful suggestions other than to say that I have the
same hardware and experienced the same problem.  This is probably worth
filing a bugzilla report over, but I have no idea how to reproduce the
problem.
